More on Dave's 16" F4.5 . . .

A 9-point flotation mirror cell designed and optimized
with plop. All aluminum construction and large
collimation bolts for stability and easy of adjustment.

Dave asked for "wheel barrow" handles to move his
16" telescope more easily. An effective and elegant
answer -- 10" pneumatic tires on black anodized
handles. These are "removable" of course

A solid 3/8" axle for stability and long life!!

Now to add some color and varnish. That's the focuser

Easy Transport Telescope option.

Thanks, Robert, for the photo of you
and the telescope. Looking great!!

Destination Moon .....

I  happened upon this video on Youtube about making the film Destination Moon in 1950. In it, we meet George Pal (producer of this and other science fiction films), Robert Heinlein (science fiction author) and Chesley Bonestell (science artist and author).  I saw this film when it was first released and dozens of times since then!!

Check out this link. Click HERE.

A Neat Idea from Curt in Redmond, Washington...

Storing the top ring on a truss telescope has been made
easy by Curt with his adapter-ring and short struts.

Great idea, me thinks!!!

And, yet another view...

A Rocker for Chris' 17.5" Telescope . . .

Accommodating Chris' 21" spider means scaling up the
size of the telescope a bit. Here's the rocker box 
coming together.  The dimensions are a "bit" larger 
with a 27" foot-print. Nice!!

More on a 17.5" Kit for Chris...

Most of the kit is complete. I just need to make the
rest of the rocker box and mirror cell.

And, the "top ring" with spider brackets for a
4-vane Protostar spider and focuser bracket.

Chris' 17.5" Truss ....

The 26" diameter altitude bearings and rocker box sides
are taking shape. So far, this kit is looking great!!

A Secondary Mirror Cover in a Jiffy . . .

Curt, in Redmond, Washington sent along this neat solution
for a secondary cover. First, of course, one has to "eat the
the contents"!! Great idea....

And check out the very cool color of his 12" telescope.

An 8" Mirror Cell for John in Tuscon, Arizona....

Here's a "simple 6-point" cell for John's 8" primary mirror.
The O.D. of the backplate is 9.5". His mirror is 1.5" thick,
so a simple all Baltic birch cell will work just great.

Easy collimation with thumb knobs. John will affix his mirror
to the cell with silicone. No mess, no fuss.

A Custom 8" Rocker Box and . . .

A custom rocker box and altitude bearings
for Robert in San Rafael, California.

Just send me your tube-rings and
I'll do the rest!!

Hi Dennis

I thought I would send you a quick photo. I have mounted the dobstuff telescope on a Gregg Blandin crossbow platform. I have used the platform for my old GSO 10", but with a minor adjustments to the feet of the rocker box, it easily accepts the new telescope. Weight is not an issue - the crossbow is built like a tank! So, now after painstakingly centering Mars in a high powered eyepiece, I can amble inside and coax my wife out in the cold for a look. A polar cap and surface detail were clear through some fairly murky viewing. She was very impressed! She laughed at the size of the scope compared to the old one, and I do need a ladder for this view, but I think a will get a simple 12 inch step stool and that will do just fine.

Thanks again for producing such a fine instrument, and in record time!

Best wishes
